Chapter 1 - Overview
1-7
External Setpoint
Relays Card (-D3) The same as the -D2 option except that the length of the cable provided
is six inches. This is designed to mount in the HI 2151/30WC-WS-D3
wall mount enclosure.
Miscellaneous Options
240 VAC 50/60 Hz
Input Voltage (-E2) This is a factory configuration only.
NIST/NTEP
Certification Mode
Kit (-E3 except for -
F4 wall mount) The HI 21251/30WC is approved for National Institute of Standards
and Technology (NIST) applications formally called the National
Bureau of Standards (NBS). It is certified under the National Type
Evaluation Program (NTEP) for up to 10,000 counts when the NIST
mode is activated. This option is required when products are to be
directly sold based on weight readings of the scale. This kit includes
special screws for sealing the instrument, a label plate, a NEMA 4 gas-
ket and a NIST label.
Portable Display and
Keypad (-E4) The HI 2151/30XX-E4 option is used for local set-up, calibration and
display of the blind remote version instrument, modelHI 2151/30WC-
BR.
Intrinsic Barrier
Assembly (-F8) The Intrinsic Barrier Assembly Option is used with the Model HI 2151/
30WC. The option provides safety for Class I, II and III, Division I
Applications. Only the front face panel is rated for Class I and II Divi-
sion II areas. The remaining portion of the HI 2151/30WC controller
must be installed in a NEMA4 enclosure for an intrinsically safe area.

Interpreting the
Model Code Number
Model Code
Breakdown The model code number can be found on a label that is attached to the
HI 2151/30WC. It starts with the base model number (HI2151/30WC).
Fig. 1-1 shows dash alphanumeric code designations that indicate the
capabilities of the weight controller. For example: A model HI2151/
30WC-A1-C2-D1-E3 is a Panel Mount Instrument with a factory-con-
figured RS 232 serial port, rate-of-change, six TTL level outputs, and
an NTEP Certification Kit.
